Description

Technical field

This invention relates to a refrigerator with a drawer.

State of the art

Drawers of this type are often molded from plastic and can reach significant dimensions in width and depth in accordance with the internal dimensions of the refrigerator in which they are used. These drawers are subject to deformation both in their manufacture and in subsequent use. Excessive deformation leads to the formation of cracks and ultimately to breakage of the boxes.

Improving the stability of the mold by increasing the wall thickness leads not only to high material costs; at the same time, it is also possible that strong stresses arise in the walls themselves, leading to the fact that the boxes immediately after casting are deformed and become unusable. The consequence of this may also be a premature increase in fragility. A thin-walled drawer, when using it, requires reinforcement from below over the entire plane so that it does not deform under the load of its contents, which leads to the fact that such drawers, although reinforced over a large area, are used mainly directly on the bottom of the refrigerator.

Disclosure of invention

The objective of the invention is to create a drawer for a refrigeration apparatus, which at low costs for its manufacture withstands loads and maintains a stable shape.

The problem is solved by a refrigerating apparatus with a drawer having a bottom plate and side walls surrounding the bottom plate, in which ribs are provided between the two side walls and extend at least some distance from the bottom plate and are located at least approximately on one line. Rib-shaped sections arranged sequentially on the same line at a distance from each other serve to provide bottom rigidity. If the edge-wide sections in the form of ribs are additionally connected with the side walls, then along with the bottom, rigidity is also attached to the drawer as a whole.

The rib-shaped sections are particularly effective in affecting the rigidity of the bottom of the drawer when they are connected into a solid rib that extends continuously.

In order to reduce the useful volume of the drawer as little as possible, the rib preferably extends into the interior of the drawer. You can also imagine a rib extending from the bottom down, however, its drawback is that the space below the bottom on both sides of the rib is unlikely to be used to place cooled objects.

A stiffener of this type is useful, in particular, in drawers in which the third side wall has a recess. Such a recess may be necessary, for example, in order to fit an air duct extending from the wall into the interior of the refrigerator, through which air circulates between the interior and the evaporator chamber separated from the interior. For such a drawer it is especially advisable if the first rib touches the concavity.

Openings on top of the recesses formed in the rib can be used to place bottles, cans or other substantially cylindrical objects in them to prevent them from rolling off

To enhance the stabilizing action parallel to the first rib, a second rib or several additional ribs can be provided.

The second rib can also have recesses open at the top, the lower points of the recesses of the first rib and the recesses of the second rib are preferably in a plane parallel to the first and second side wall, in order to fix a cylindrical object in them parallel to the two side walls

The lower points of the recesses lying in a plane parallel to the same side wall, it is advisable to place at different distances from the bottom, so that, for example, to put a thick part of the bottle in the recess of one of the ribs, and its neck in the recess of the other rib.

It is possible to carry out a horizontal support arm on each of the side walls of the drawer of the drawer, which serves to suspend drawers between the side walls of the refrigerator with the possibility of extension. The support arms are preferably formed on the first and second side walls, between which the first stiffener or further ribs, if any, extend.

A subject of the invention is also a refrigerating apparatus with side walls, between which a drawer of the above type is suspended

Brief commentary on the drawings

Further features and advantages of the invention result from the following description of embodiments referring to the accompanying drawings, in which:

figure 1 is a perspective view of a first embodiment of a drawer according to the invention;

figure 2 is a second embodiment of a drawer; and

figure 3 is a fragment of a refrigeration apparatus according to the invention with a drawer, partially in front view and partially in section.

The implementation of the invention

The drawer shown in FIG. 1 is a solid molded plastic product and includes a rectangular bottom 1, which is surrounded by side walls 2, 3, front wall 4 and rear wall 5. A concave is formed in the rear wall 5 and in the bottom 1 region 6, into which, when the drawer is placed in the refrigerating apparatus, a protruding element of its rear wall, for example a cold air duct or the like, is included.

The horizontal support arm 7 extends along the side walls 2, 3 from the rear wall 5 almost to the front wall 4. When the drawer is placed in the refrigerator, the support arms 7 lie on horizontal ribs extending from the side walls of the refrigerator, with the possibility of movement along them.

A niche-handle 8 is formed on the front wall 4 for extending the drawer.

The bottom 1 is reinforced for stiffness with a hollow rib 9 open at the bottom, in a cross-section undulating, continuously extending from one side wall 2 to another side wall 3 and in the middle section connecting to the concave region 6 of the back wall 5. The rib 9 strengthens the bottom 1 and prevents it from bending under load, which in extreme cases could lead to slipping of the support arms 7 from the ribs of the refrigeration apparatus. Due to the wavy rounded cross-sectional shape of the rib 9, the presence of the rib 9 does not create in the drawer hard to reach and poorly cleaned corners. Due to the absence of sharp edges in the rib 9, the risk of dents or other damage to the cooled objects that are pressed against the rib 9 in the box is also minimized.

FIG. 2 shows a second embodiment of a drawer, the appearance of which is similar to that of the drawer in FIG. 1, so that the same parts in FIG. 2 are designated the same as in FIG. 1, and are only explained to the extent that this is necessary to understand the differences from the first embodiment. In the drawer in figure 2 between the two side walls 2, 3 are three parallel to each other ribs 9-11. In general, the number of ribs may vary depending on the required degree of rigidity of the bottom 1, however, however, the flat sections of the bottom 1 between adjacent ribs 9, 10 or 10, 11 should have been significantly wider than the height or width of the ribs in order to allow the gap to be used between ribs 9-11 to accommodate cooled items.

In figure 2, the ribs 9-11 have recesses 12 open at the top, which have an arcuate shape in cross section, with the lower points 13 of the recesses 12 of the different ribs located one after another located in a plane perpendicular to the longitudinal direction of the ribs 9-11. The recesses 12 of the ribs 10, 11, respectively, have the same radii that are larger than the radius of the recesses of the ribs 9, and their lower points 13 are located closer to the bottom 1 than such points of the ribs 9. Thus, it is conveniently placed in the recesses 12 of the ribs 10, 11 thick parts of the bottles, and in the recesses of the ribs 9 - the neck of the bottle, thereby preventing the bottle from rolling off.

Figure 2 shows two recesses 12 in each of the ribs 9-11, however, it is clear that the number of recesses 12 may be different depending on the width of the drawer.

Figure 3 in its left half shows a view of the open front side of the refrigerator with a drawer suspended in it, while in the right half shows a section of the refrigerator and drawer. It can be seen that several horizontal ribs 15 extend from the side walls 14 of the refrigeration unit into its internal space 15. On the ribs 15 opposite each other there is a shelf 16, on the next pair of ribs 15 located below, a drawer 17 is suspended. In a section in the right half of the drawing, two ribs 9, 10 located one after the other, and the rear rib 9, which in its middle section is connected to the concave region 6 in the rear wall of the drawer, has a greater height and recesses 12 of smaller radius than the ribs located in front of it o 10. The number 18 denotes a bottle held in a group of recesses 12.
